The two DNA strands are held together by interchain hydrogen bonds. H-bonds pair the bases in one chain to the complementary bases in the other chain. (A/T and G/C).

The hydroge â¦ n bonds of DNA are analogous to the rungs of a twisted ladder. The sugar-phosphate backbones of the double helix are analogous to the sides of a twisted ladder.
